摘要 本文从政策不确定性的视角探讨中国经济转型过程中企业杠杆率变动背后的逻辑。在基于2002—2016年A股上市公司的季度数据描述企业杠杆率结构性变化的经验事实以及理论分析的基础上,运用Baker et al. (2016) 构建的经济政策不确定性指数实证分析政策不确定性与企业杠杆率之间的关系。结果表明,经济政策不确定性对企业杠杆率具有显著的负向影响;这一负向效应在短期负债率、民营、小规模和制造业企业更为明显。进一步考虑经济转型的扩展分析发现,政策不确定性对企业杠杆率的负向影响会随着地区市场化水平的提高、民营化改革的推进和对外开放度的扩大而显著降低。本文的研究对深入理解企业杠杆率变化背后的逻辑以及科学地制定供给侧结构性改革相关政策具有现实意义。

Summary:  With the Chinese economy entering a “new normal” and undergoing transformation, the scale of debt and potential risks have increased rapidly. The central government has paid close attention to this. At the Central Working Conference in 2015, “de-leverage” was listed as one of the five major tasks of supply-side structural reform. How to de-leverage has become a focus of attention and discussion in all sectors of society. Studies mainly focus on the factual changes in corporate leverage and less on the logic behind these changes. Considering that China is in the process of transforming from a planned economy to a socialist market-oriented economy, the government may still intervene through various economic policies. Frequent economic policy changes may increase the uncertainty of economic policies. Economic policy uncertainty is an important source of external environmental uncertainty that enterprises in transition economies face and may affect corporate financing decisions. This issue is worthy of more attention and in-depth study in China, which is undergoing an economic transformation.
We link economic policy uncertainty from the macro perspective to micro-level corporate financing decisions. We also explore the logic behind the change in the leverage of enterprises in transitional China from the new perspective of policy uncertainty. First, we use the quarterly data of listed companies from 2002 to 2016 to describe the empirical facts of structural changes in corporate leverage and carry out the corresponding literature review and theoretical analysis. We then use China’s economic policy as constructed by Baker et al. (2016) to empirically analyze the relationship between policy uncertainty and corporate leverage. The main results show that the higher the uncertainty of economic policy is, the lower the leverage ratio of enterprises is. For every 1% increase in economic policy uncertainty indicators, the average leverage of firms decreases by 0.03 to 0.07 percentage points. This negative effect has obvious structural characteristics, which are even more significant in the samples of short-term debt ratios, private enterprises, small scales, and manufacturing companies. Furthermore, considering the economic transformation background of the region in which an enterprise is located, the model is extended and analyzed. We find that the negative effect of policy uncertainty on the leverage ratio of enterprises decreases significantly as the regional marketization level, the gradual advancement of the privatization reform, and the degree of openness increase. The above conclusions demonstrate strong robustness when examining endogeneity problems, replacing key variables, and setting various models.
We mainly extend the literature in two aspects. First, we explore the logic behind the change in the leverage ratio of Chinese enterprises from the new perspective of policy uncertainty andenhance the research on the interaction between macroeconomic policies and micro-enterprise financing behaviors. However, we do not focus on a specific economic policy, but on the perspective of the uncertainty of the overall economic policy, and further expand the literature on existing policy evaluation. Second, using the quarterly data of Chinese listed companies provides comprehensive and meticulous empirical evidence for the impact of economic policy uncertainty on corporate financing behavior. This is especially true for examining a series of reform variables, such as marketization, property rights reform, and opening up, in the process of economic transformation.
Our conclusions have direct policy implications. First, in implementing the de-leveraging policy, it is necessary to clarify the structural and time-varying characteristics of leverage, to fully recognize the impact of policy uncertainty on the polarization of corporate leverage, and to prevent the development of a “one-size-fits-all” de-leveraging policy. Second, reducing or mitigating the negative impacts of government intervention and policy uncertainty on corporate financing decisions relies on the further reform of China’s economic system.
